/W ATTORNEY Patented Apr. 19, 1932 UNITED STATES GEORGE W. DANIEL, OF CHICAGO, ILLINOIS ens RANGE Application filed May 12, 1931. Serial No. 536,868. i

The object of the invention is to provide a gas range containing an oven in which the heating means is so arranged that the oven is uniformly heated throughout; to provide a gas range in which oven heaters may be ignited without undue effort on the part of the user; and to provide a device of this nature which is of simple form and therefore susceptible of cheap manufacture.

With this object in view, the invention consists in a construction and combination of parts of which a preferred embodiment is illustrated in the accompanying drawings, wherein:

Figure 1 is a perspective view of a range constructed in accordance with the invention.

Figure 2 is a horizontal sectional view.

Figure 3 is a perspective view of the oven heater, the outline of the range being indicated in dotted lines.

Figure 4 is a sectional view on the plane indicated by the line 44 of Figure 3.

The heater for the oven consists of a pipework frame comprising the upper and lower burner pipes 10 and 11, the vertical burner pipes 12, the horizontal feed pipe 14 and the vertical feed pipes 15, all of which are interconnected by Ts and corner Ls as indicated at 16 and 17. This arrangement disposes a burner pipe 12 in each of the four vertical corners defined by the end walls 18, front wall 19 and rear wall 20 and also disposes a burner pipe 10 in the front and rear corners defined by the top wall 21 and front and rear walls 19 and 20, a burner pipe 11 being correspondingly disposed in the corners defined by the bottom wall 22 and front and rear walls.

The front and rear walls 19 and 20, the end walls 18, the top wall 21 and bottom wall 22 are formed of sheet iron and each consists of dual laminae with an interposed heat insulating sheet of asbestos 23. The several walls are secured to and are supported by vertical standards 24 made preferably of angle iron extending below the bottom wall a short distance to provide legs by which the range is supported in spaced relation to the floor or other supporting surface.

the pilots The angles also'eXtend beyond thetop wall to act as a support for the top casting 25 and dispose the latter in spaced relation to the top wall 21 of the oven, so that space may be provided for the burners 26 .below the grates 27 which are carried by the top casting and which act, as ordinarily, as supports for cooking receptacles to be disposed above the burners 26.

The burners 26 are connected with thesupply pipe 28, each having its own control valve 29, the feed pipe 28 being extended, as indicated at 30, for connection to a gas supply source. There is also connected with the feed pipe 28, the oven supply pipe 31 which is I coupled to the supply pipe 14 at its point of juncture with one of the vertical distributing pipes 15 and a control valve 32 is disposed in this pipe 31.

Pilot lights 33 and 34 are disposed in the oven at the centers of the top and bottom walls and are connected with a feed pipe 35 which in turn is connected with the supply pipe 28 by a branch 36 in which is disposed a button valve 37. In its normal position, the button valve permits the passage of a minimum amount of gas to maintain the pilots lighted but when it is depressed, the feed opening is materially increased, so that the supply to is sufficient to cause flames to be directed by the upper pilot 33 towards the burner pipe 10 and by the pilot 34 towards the burner pipes 11, the vertical corner burner pipes being also lighted from these pilots, when the valve 32 is opened. Release of the button valve 37 will restore it to its normal position leaving the pilots supplied only with sufficient gas to maintain them lighted.

Racks 38 are adjustably supported in the oven to receive receptacles containing what- 0 ever it is desired to bake and access to the oven is had through the medium of a swinging door 39 hingedly mounted in and olosing an opening formed in the front wall 19.

The provision of the burner pipes in the oven at the corners thereof makes for an even distribution of the heat throughout the oven and requires but a minimum of gas to maintain the desired oven temperature. 1

The invention having been described, what is claimed as new and useful is: I 1. A gas range comprising an oven of rectangular form, and a heating unit disposed in the oven and consisting of interconnected burner pipes of which one is disposed in each of the vertical corners and the remainder in the corners formed by the bottom and the side walls and the top and the side walls.

2. A gas range comprising an oven of rectangular form, and a heating unit disposed in the oven and consisting of interconnected burner pipes of which one is disposed in each of the vertical corners and the remainder in the'corners formed by the bottom and the side walls and the top and the side walls, and

' pilots disposed adjacent the top and bottom walls and positioned to direct flames to the burner pipes.

In testimony whereof he afl'ixes his signature.
